Abstract :
An 8-bit 250MSPS flash A/D converter using 0.35mum BiCMOS process is presented in the paper. A novel sample-and-hold amplifier is used to improve sampling rate of the A/D converter, and the amount of input capacitors and equal resistor network is reduced by using an interpolating technique. Tri-input AND gate, latch and coding network are designed to overcome bubble and sparkle codes. Operating at 3.3V supply voltage, the A/D converter has a signal-to-noise ratio (SNR) of 47.3dB and it dissipates 561mW of power.
